MULTI-CAMERA HEAD

1 . A multi-camera head, comprising:

a head frame;

a plurality of stereo cameras mounted to the head frame and arranged around an axis; and

at least one stereo camera mounted to a top of the head frame, and across the axis.

2 . The multi-camera head of claim 1 , wherein the plurality of stereo cameras are pitched toward the axis at a pitch angle relative to vertical.

3 . The multi-camera head of claim 2 , wherein the pitch angle is in a range of between about 5° to about 15° relative to the vertical axis.

4 . The multi-camera head of claim 2 , wherein the pitch angle is in a range of about 10° to about 12° relative to the vertical axis.

5 . The multi-camera head of claim 2 , wherein the pitch angle is about 11.25° relative to the vertical axis.

6 . The multi-camera head of claim 1 , wherein at least one of the stereo cameras includes two lenses in a plane, where the two lenses are offset at an angle relative to a horizontal axis of the plane.

7 . The multi-camera head of claim 6 , wherein the offset angle is about 45°.

8 . The multi-camera head of claim 1 , wherein each of the plurality of stereo cameras includes two lenses in a respective plane, where the two lenses in each respective plane are offset at an angle of about 45° relative to a horizontal axis of the plane.

9 . The multi-camera head of claim 1 , wherein the plurality of stereo cameras is four stereo cameras.

10 . The multi-camera head of claim 1 , further comprising:

a body disposed between at least two stereo cameras from the plurality of stereo cameras.

11 . A multi-camera head, comprising:

four stereo cameras mounted to four respective sides of a head frame and arranged around a vertical axis; and

an elongated body disposed between a first pair of adjacent sides of the head frame and a second pair of adjacent sides of the head frame, each side of the head frame comprising a stereo camera from the four stereo cameras.

12 . The multi-camera head of claim 11 , further comprising:

at least one stereo camera mounted between the four stereo cameras, and across the vertical axis.

13 . The multi-camera head of claim 11 , wherein the four stereo cameras are pitched at a pitch angle toward the vertical axis.

14 . The multi-camera head of claim 13 , wherein the pitch angle is about 11.25° relative to the vertical axis.

15 . The multi-camera head of claim 11 , wherein camera lenses in at least one stereo camera are offset at an offset angle relative to a horizontal axis.

16 . The multi-camera head of claim 15 , wherein the offset angle is about 45°.

17 . The multi-camera head of claim 11 , wherein the multi-camera head is coupled to a robotic vehicle.

18 . The multi-camera head of claim 11 , further comprising:

at least one light stack configured to generate outputs indicating a predetermined condition or state.

19 . A computer-implemented method of analyzing a pitch angle of a plurality of stereo cameras disposed around an axis in a multi-camera head, the method comprising:

modeling the multi-camera head as a point source at a center of a computer generated sphere, including defining a field of view of each stereo camera;

entering a pitch angle for each stereo camera;

graphically modeling the sphere; and

graphically projecting a field of view of each stereo camera onto the sphere.

20 . The method of claim 19 , wherein the multi-camera includes a top stereo camera disposed across the plurality of stereo cameras disposed around the axis and the method further comprising:

graphically projecting a field of view of the top stereo camera onto the sphere.

21 . The method of claim 19 , further comprising:

in response to a user input altering a pitch angle of at least one stereo camera, graphically re-projecting the field of view of each stereo camera onto the sphere to display the altered pitch angle.
